dualsense on PC is barely unuseable

Hello Battlefield developers, I have noticed that the DualSense controller has serious performance issues on PC.
When I used the Dualence Edge controller and Xbox Series X controller on my PC, I found that the Dualence Edge joystick has only eight directions, which is particularly deadly for FPS games that require precise target positioning. I asked my friend playing on PS5 and received feedback that he did not encounter this issue. I suspect it may be unique to PC.
Another thing troubles me is that even though I have set zero dead zones in both the game and PlayStation Accessories , there are still certain dead zones that I cannot operate
These two questions above are definitely present in the game.The following questions I havent study whether or not is in the game or something else,just doubt it 
One thing is that there may be a possibility slight rotation in the viewing angle after the right joystick returns to center. It keeps rotating, both my XSX controller and DSE will encountered .I did not turn on Steam input and neither of my controllers is broken. 
The second thing is that I think the current joystick curve is not purely linear , but i cant prove it to you ,just a starnge feeling.
I really love this game and hope it gets better. I hope the developers can fix this performance issue as soon as possible. Thank you for your efforts
